UPVC vs Aluminium Windows: Expert Advice on Which to Choose

Whether to choose UPVC vs aluminium windows depends on factors like installation location, budget, and personal preference. Aluminium windows are highly durable, heat-resistant, and weatherproof, but usually cost more. UPVC windows, especially reinforced UPVC, are more affordable, provide good sound and heat insulation, though they may not last as long as aluminium.

This article will help you compare UPVC vs aluminium windows so you can choose the best option for your space.

1.Comparing UPVC vs Aluminium Windows Based on 5 Key Criteria

1.1. Durability and Material Construction

Aluminium Windows: Made from aluminium alloy, these windows are highly durable and naturally corrosion-resistant thanks to a protective oxide layer on the surface. The aluminium profiles are designed with hollow chambers to reduce weight while maintaining strength. Aluminium does not suffer from termites, warping, or shrinking under weather changes.

UPVC Windows: Made from PVC or uPVC (lead-free plastic), with some premium models reinforced with steel for added strength. The multi-chambered profile structure provides excellent thermal insulation, but the mechanical durability is lower than aluminium. If the plastic is recycled or lacks UV-resistant additives, it can yellow, become brittle, and break after a few years of exposure to sunlight and weather.

1.2. Strength and Weather Resistance

Aluminium Windows: Thanks to the strong and durable nature of metal, aluminium windows have excellent structural strength. They can be made in large sizes or wide openings without extra reinforcement bars. Ideal for high-rise buildings where wind pressure is strong. The anodized or powder-coated surface ensures long-lasting beauty, scratch resistance, and color stability under harsh weather conditions.

UPVC Windows: Weather resistance is good, but the material may expand or contract under sudden temperature changes. UPVC has limited stiffness and load-bearing capacity, making it prone to sagging if not properly manufactured. Best suited for standard-size doors and windows.

1.3. Sound and Thermal Insulation

Aluminium Windows: Aluminium is a metal and conducts heat easily, so external temperatures can quickly transfer indoors. To improve insulation, it needs thermal break systems, double-glazed glass, and high-quality rubber seals for better sound and heat insulation.

UPVC Windows: UPVC excels in soundproofing and thermal insulation due to its low thermal conductivity and multi-chambered profile structure. Ideal for areas requiring quiet environments or energy efficiency.

1.4. Aesthetics and Architectural Style

Aluminium Windows: Offers a modern and luxurious look with powder-coated finishes in many colors. Can be made in large, complex designs while remaining strong, fitting modern, minimalist, industrial, or high-tech architectural styles.

UPVC Windows: Features a variety of colors and patterns, including realistic wood grain finishes. Suitable for both classic and modern styles, though it may not achieve the same level of elegance and premium feel as aluminium.

1.5. Price and Lifespan

Aluminium Windows: Initial cost is higher than UPVC windows, starting from around 2,500,000 VND/m². Prices increase further for imported aluminium or thermal break systems. However, aluminium windows have a very long lifespan, often lasting several decades with proper maintenance.

UPVC Windows: Initial cost is lower, starting from around 1,500,000 VND/m². Suitable for projects with a limited budget or temporary use. UPVC windows last about 15–25 years, depending largely on the quality of the profile.
